I'm about to go ballistic.
Over the last year Ive been having a consistent intermittent no start issue with my 06 950 adv.
sometimes it just wont start. No starter motor.
So I started to disable switches to get to the bottom of what is going on. I do not have a schematic, that would probably help a lot.
So far I have jumped the clutch wire. removed the side stand switch,
and also cleaned the contacts on both the ign switch and start button. also checked the relay.
I just finished cleaning and stretching the springs in the neutral safety switch as well.
Same issue intermittent no starter, no click nothing.
I can unplug the Neutral safety switch and also still have the intermittent failure,
If I kick the shifter in toward the motor it seams to work, even with the NSS unhooked?? WTF is that.. I need a beer.
Anyone have any ideas??

If you have disabled the sidestand and clutch switches, you may as well bypass the starter auxilliary relay as well.
You need to find out if 12v is reaching the starter relay coil, and if the ground is good and the relay is clicking, then either the relay contacts are bad, or the starter is bad.

Have you checked the starter relay? (this is the one close to the water pump)

Also, just as the horn botton, the start botton may create some bad contact on it, take it apart, clean the two mating parts (making sure they are paralel as posible, pretty much like the fuel pump points) and see if is that.

Do you have the side stand relocator? which one? check to see if in the instalation any wire got bangged or whatever

use it at the start relay to see if there is battery voltage present from the start button circuit when the start button is pressed AND the fault is occurring... If there is, then its the solenoid... if not then start working your way back up the chain... there are several "safety" latching relays on the upper fairing left side and there are some diodes there to... You need to have a schematic to be able to easily troubleshoot this so that you are not poking around in the dark trying to stumble across the issue.

Thanks
Ive done all of the above. I found the How to not quite cover many issues Ive seen with this same issue.
Special thanks to AdvRonski for the schematic
That will put an end to it.
Maybe it will start for race day.

Huge Thanks to Kennyd who sent me a PM telling me about his bike that had a wire come out of a connector in the harness.
Turned out my bike had the same issue.
Its very tough to troubleshoot intermittent electrical issues, even for an old experienced salt. Without Kennyd's input I could have spent another day pulling my hair out and waking up with a hangover.
Thank You ADV Rider!!!!!
I'll be racing on Sunday!!!

Glad to hear your bike is up and going again. Would you post a picture of that location of the loose wire? Thanks !

I didn't think to take any photos. Sorry.
There is a small white connector(red/white wire) under the dash on the top of the connector rail. left side.
It looked to be good and then fell apart in my fingers while under inspection. Soldered the wire and all is well.
